On the taxonomy of the genus Nannocalanus Sars, 1925 (Crustacea, Copepoda: Calanidae)

V.N. Andronov

Abstract. Nannocalanus elegans sp. n. from the Southeastern Pacific is described and illustrated. Females of this species differ from those of N. minor (Claus) in the shape of the body, outline of the general segment (in lateral view), and relative size of valve flap. The inner edge of B1 P5 of males and females is with 9-17 denticles (average 12-13), while with 13-26 denticles (averlage 18-20) in N. minor from the same locality. The inner edge of left B1 P5 is entirely serrated in males of N. elegans, but without denticles in the distal 15-20% of its length in N. minor. Sewell’s (1929) N. minor f. major and N. minor f. minor from the Indian Ocean are probably distinct species.
